Pro Micro port/pins

Development Boards Arduino

Hi all, I have a question about Pro Micro.

I’ve seen the Pro Micro pinout diagram on the Sparkfun site, but what I need to know is what port/pin on the atmega32u4 each Arduino pin corresponds to. I want to try some direct port manipulation. Any suggestions please?

Thanks,

Paul

If you look at the schematic for the Pro Micro (link on Sparkfun’s Pro Micro product page) you can see the pinout. Trace the signal names back to the Atmega physical pins. Then look in the Atmega data sheet (link also on Sparkfun’s Pro Micro product page) for those pin functions and control registers.

Good luck,

Chip

Thanks Chip. I managed to find a diagram of the atmega32u4 showing the port/pin numbers which had also been annotated with the Arduino pin numbers for the Leonardo. I am told this same mapping applies to Pro Micro too, is that correct?
